-New VisIt simulation control interface in weipa (uses VisIt's simv2)
-Rewrote restarts.py to be a more generic data manager for restarts and exports
-Removed weipa python file since the functionality is now handled by restarts.py

bin/escript:
- bail out early if buildvars is not around
- quote variables to avoid syntax errors

- escript -V was still spitting out 'pre2.0' -> changed to pre4.0
- fixed minor typos

Updated install guide to include the correct version of python.
Updated Mac build instructions not to use numarray or frameworks.
Removed (commented out) references to MacPorts in the Mac instructions.

CSIRO won't have a windows release ready yet.

Modified wrapper script to correctly point at numpy in standalone builds.
Updated build from source doco for linux to take numpy into account.
Also removed backticks in favour of $() - it should be the same but latex won't eat them

The wrapper template is no longer used.
Extraneous output doc removed from scons during build.
note: finleypython is no longer built (it was deprecated anyway).
